Instead of creating a bunch of minor issues, I thought that it may be better to group some of my more nitpicky suggestions for the docs here. If I missed or misunderstood some documentation, please let me know.

• \pahfit\pahfit\docs\file_formats.rst mentioned power as an input for "line" and "dust_feature", but I don't see anything for power in the yaml files. It might be worth clarifying that the default yaml file doesn't use it.
• We still have ipac tables in the \pahfit\pahfit\packs\science folder. Should they still be there? I don't think that the docs explains their presence to new users\that they should avoid using them in the dev branch (?)
• This isn't specifically related to PAHFIT, so you may not wish to include it. However, as someone who mainly uses conda to manage packages (and who still has a lot to learn about managing packages/environments), I'm not sure how best to handle installations using pip. Should pahfit\pahfit\docs\install.rst have any warnings/tips for conda users?
• Would it be useful to have some documentation page that keeps track of the main purpose of each .py file, and briefly explains how they tie into each other? While trying to follow the code, I sometime find it hard to figure out how the different files tie into each other/where a function is located. Having a page that gives an overview of the code (or even just lists the names of all the methods/functions of each file in point form) may make it easer for new contributors to get started. It would also make locating methods/functions easier when debugging/updating.
